Are the motors in new energy vehicles AC or DC?
1 Answers
The power battery in new energy vehicles is DC, while the motor is generally a permanent magnet synchronous AC motor. Function of electric vehicle generators: The popular motors used in current electric vehicles are DC before entering the regulator and AC when entering the motor. The regulator performs frequency conversion, and a 220V inverter similarly first converts to DC and then to AC to change the frequency. Working principle of new energy vehicle motors: By periodically reversing the polarity of a set of electromagnets, switching between north and south poles, the motor utilizes these attractive and repulsive forces to rotate the shaft, thereby converting electrical energy into torque to turn the vehicle's wheels. Conversely, in situations like regenerative braking, these magnetic or electromagnetic forces can convert motion back into electrical energy.
